使用续集

Question

我尝试使用Sequelize ORM。阅读有关文档，我看到了示例

const Project = sequelize.define('project', {
title: Sequelize.STRING,
description: Sequelize.TEXT
})

const Task = sequelize.define('task', {
title: Sequelize.STRING,
description: Sequelize.TEXT,
deadline: Sequelize.DATE
})

我解决了在shell节点中实际应用的问题。 我在命令行中启动了节点

var sequelize = require('sequelize')
sequelize.define ...

但是结点说我错了，续集没有方法“定义”。 所以我认为现在我的错误在哪里，我错了理解文档

您需要创建一个sequelize实例：

const Sequelize = require("sequelize");

const sequelize = new Sequelize(
  database,
  username,
  password,
  {
    host: host,
    logging: false,
    dialect: "mysql",
    port: 3306,
    pool: {
      max: 5,
      min: 0,
      idle: 10000
    }
  }
);

然后定义：

const Project = sequelize.define('project', {
title: Sequelize.STRING,
description: Sequelize.TEXT
})

const Task = sequelize.define('task', {
title: Sequelize.STRING,
description: Sequelize.TEXT,
deadline: Sequelize.DATE
})
